[RFC PATCH 05/10] qemu_capabilities: Added capability for qemu's "ebpf_rss_fds".

[Andrew Melnychenko]

Added check for qemu virtio-net "ebpf_rss_fds" property.
This property allows to pass eBPF program/map file descriptors for RSS program.
In other patches, libvirt may launch qemu-ebpf-rss-helper and pass fds
to virtio-net qemu.
